' LSE AND CR'ANK CASE FOR HYDRUCAREOII-E Spcification of Letters Patent Application filed May-21, 1906. Serial No. 318,855.

To all whom it may concern:

Be it known that I, HENRY B. JOY, a citizen of the United States, and resident of Detroit, li nyne county, State of Michigan, have invented certain new and useful Improvements in Bases and Crank-(loses for Hydrocnrbon-l lngines, of which the following is o specification.

This invention relates to various im )rovoments in means for supporting and lu ricating' hydrocarbon engines and more particularly to the crank case and its Various adjuncts. j

The invention will no described in connection with the accompanying drawings, in which,

Figure 1 is a plan View of the engine base and ornnk case, the engine cylinders being removed; Fig. 2 is n side view of the some partly in section through the crank shaft bearings, Fig. 3 is a top plan View of the middle. section ofthe crank case; Fig. 4 is a top plan View of the bottom section of the crank case; Fig. 5 is an end View, the cover or end plate of the gear case being removed; and Fig. 6 is a section on the line 6-6 of Fig. 1, the crank being shown in diilerent position. i

Referring to the drawings the upper sec tion A of the crank case is provided at one end with opposite outwardly extending arms A, the extremities of which rest upon the frame members i, which, for instance, may be the side members of the frame of on on tornohiio.

While my invention is primarily intended for use in automobiles, it is applicable to hydrocarbon engines for motor boots and other purposes and the frame. members 1. insy, for instance, be suitably connected to the frame of a motor host. it the opposite end of the casing section A are hollow arms A the outer ends of which are also adopted to-rest on the frame members, 1. There is a continuous compartment or chamber extending throughout the arms A in which n scries'ot gears, hereinafter referrsd to, are mounted, and this compartment or chamber is closed by means o plate 2 fastened in position by suitabis screws or bolts, as shown in Figs. 1 and 2.

Errtending between the arms ii, A", on each sizie of the section A, and from the seotion A. to the frame member 1, n. WSiD- or plate forming sshield for preventing dust able means, such as screws or bolts.

while the 1m est section J dorm hiii.

dition to their function as shieids. it v. noted that the side from members, the i tionA, the supporting arms, and the shi I form the sides and bottom or" the in of the housing Within which the located.

Beneath the casing section A second section B, the two having flange-ii roostir edges and being sepsrzihl connectod'by suit the section B of tl e casing dish-s 1 section E which covers the imrer opening the section B, the in ol' the soctions B and being also rletnchnhly oonnectccl by suitable means, such as so ews or bolts.

A ie ongi -e illustrated 's of two cilinders n bearings, two the ends of tin i:

Ti. this pa -tron 1u located tee'rsi with, the up action case; the intermediate soctioi tition connected to and preferswith the iniddie. section B of th the. bottom or era-bly integral vi he threr arm the crank case. i tions, 5, J, 5 form con separating era; 1 compartments and ese of supporting" comings nu! prove oil i-.om Y

other, as W senses bearings is formed in the upper casing section A and the other half in the intermediate section B, these sections being separable pro vide for easy insertion and removal of the crank shaft. W hen the lower section E of the case is removed, the crank shaft is fully exposed and accessible for cleaning and re pairs. The lower section is filled or nearly filled with oil when the engine is in a normal running condition and the crank shaft bearings, the pistons and the itmans are lubricated by the s lashing of t is oil as the shaft revolves rapid y. i

In the bottom of each compartment E are grooves 7 leading downwardly to a sediment pocket 8 which is preferably undercut, as. shown at 9, to prevent sediment from being washed out by splashing of the cranks. The grooves or gutters 7 are preferabl parallel with the crank shaft and the cran {S impart to the oil a movement across the grooves, the tendency of any sediment in thecil being to drop into the grooves and gradually work down into the sediment pockets 8. As often as may be necessary plug 10 is unscrewed from the bottom of the pocket and the sediment is removed.

Within the compartment 11 inclosed by the hollow arms A is a train of gears which are driven by a spur gear 12 on the crank shaft 6. The shafts of gears are supported in hearings in the end wall 13 of the crank case section The gear let isan idle gear. The gears 15 and 16 operate the cam shafts which control the engine valves while the l7 and 1 are respectively fired on ts supply power to operate auxiliary devices of the engine. The shaft 1-9 may, for instance, be used to drive a magneto to supply current for the igniting devices and the shaft 20 ma be 'usec to operate a pump to circulate the cooling water for the engine.

Having described my invention. what I claim and desire to secure by Letters Patent is, 1. In an automobile, the combination with two side frame members, of a crank-case consisting of three longitudinally-separable f ions, to wit, the section it having later- Tppxtcnded arms which are secured to side frame members, bottom dishshaped section E, and an intermediate section the section A being formed with the upper half of the era shaft bearings, and section :3 with the low ialf of said bearings.
